KEROSENE BURNER.

Application filed September 10, 1819. Serial No. 322,951.

To all whom it may corms m:

Be it known that l, JoiiN S. blows, a citizen of the United States ofAmerica, residing at Grand Rapids, in the county of Kent and State ofMichigan, have invented certain new and useful Improvements in KeroseneBurners; and i do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in kerosene generators andburners. it is an object and purpose of the invention to provide aconstruction in which kerosene may be used as a fuel and generated intoa gas for a burner, the construction being applied to stoves, furnacesOr the like, in the present case, particularly to stoves or ranges usedfor cooking purposes. A further object of the invention is to provide anovel generating, mixing and storage housing for gas which is generatedfor the burners, the same containing a reservoir, compartment in which arelatively large amount of generated gas fuel mixed with air may becontained and from which the gas passes directly to the burners where itis consumed. A still further object of the invention is to provide adevice of this character in which a plurality of burners may beconnected with and receive generated gas from said reservoir compartmentand any burner or burners which it isnot desired to use may be cut offfrom said reservoir, use being made of a very simple and easily operatedcontrol for effecting this purpose. A still further object of theinvention resides in a novel generator member such that the heavierhydro-carbon oils, as kerosene and the like, may be completelyvaporized, mixed with air and carried a considerable distance before itcomes to the reservoir, thus avoiding tendency to back-fire 1 which mayoccur should the parts where the mixed air. and fuel is burned, be closeto the air inlet. A still further object of the invention is to providea novel construction of generator tube which is equipped with devicesonthe inside thereof which may be used to remove any carbon depositswhich may form and which is an aid to generation in that it disseminatesheat throughout liquid fuel within the tube and helps maintain it ata'high degree of temperature prior to its injection lnto the mixingchamber of the device.

All of these features together with many others not specifically statedat this time, will appear fully and in detail in the followingdescription, taken in connection with the taken through the burnerhousing or casing,

the generator tube being shownin plan.

Like reference characters refer to like parts in the different figuresof the drawing.

In the construction, a hollow casting or housing is provided havingfrontand rear sides 1 and 2, a bottom' 3 and a top 4. Be

tween the top and bottoma horizontal partition 5 is located and belowsaid partition between the sides 1 and 53, a vertical partition 6 ispositioned. This divides the casting into three compartments 7 S and 9,each. of the lower compartments being about one-half the capacity of theupper compartment. The housing is completed by ends 10 and 11,supporting feet 12 and a trough 13 whichis located in front of and atthe lower part of the housing. This trough lies alongside of the side 1for a distance and is curved parat a point substantially half-waybetween I tially around the end 11 as shown. At one openings 16 are inthe same horizontal plane end of the trough and near the curved portionthereof, members 14: each having a slot 15 are cast integral with andproject from the side 1, the slots being located at a dis tance abovethe trough for a purpose which will later appear. In the side 1 at thesame height as the slots 15 a row of small holes 16 are made, beingpositioned closely to gether and extending practically the entire lengthof the trough.

An opening 17 is made in the vertical partition 6 near the end 10. Anopening 18 is made in the bottom 3 between the partition 6 and the side2 and near the end ll of the housing. The bottom 9 between. partition (3and side 2 inclines downwardly from the end 1( to the opening 18 asindicated at 3. The partition 5 between compartments 7 and 8 and nearthe end 11 of the casting, is also provided with an opening 19 which isslightly larger in area than opening 1'?', said opening 17 likewisebeing slightly larger in area than the opening 18.

In the top 4 of the casting, three openings 20 are made. Covering eachof two of them, those adjacent the ends of the casting is a housing 21integral with which is the lower part 22 of a regular gas burner. Theburner is completed by an upper member 25 radially slotted in the usualmanner, as shown. The central opening 20 is likewise covered by ahousing 251 from which a conduit 25 extends, the same being bent down topass back of the rear side 2 and connected at its lower end with ahorizontal tube 26 closed at its ends but provided with a plurality ofslots 27 in its rear side the same being spaced apart but made at closeintervals. In each of the housings 21 and 24 a shut-off valve 28 of theshape shown in Fig. 8, is located, one end having a depending handle1118Z11- ber 29 which passes through and is pivotally mounted in ahorizontally extending ledge 30 cast integral with the castingdescribed. By turning a handle 29 its coni'iected member 28 may be movedto cover or uncover the adjacent opening 20 which is located under thehousing in which the member is mounted.

A member 31 is inserted through the end 11 and into the compartment 9directly above the opening 18. The inner end of this member is bored outand threaded to receive a nozzle 32 which has an orifice, the same beingmore orless opened and closed by an adjustable needle valve 33 operatedby handle 38 A generator tube 34 has one end connected with the member31 to communicate therewith and from thence curves around the end 11 andlies along side of the side 1, being received in the slots 15 of theparts 14, heretofore described, and being spaced a short distance fromthe side and end of the casting and positioned so that the with thecenter line of the tube, At its free end the tube 3% may be engaged by ahook 35 pivotally mounted on the end of the trough 13, as shown in 5,and a coupling 36 may be used for connecting the tube in any suitablemanner with a tank or other container which holds a liquid fuel, such askerosene, under pressure.

'1 he trough 18 at the end nearest the member 31, is formed with anintegral enlargement 13 into which a fuel, such as wood or denaturedalcohol, may be entered tonicre or less fill the trough. lVithin thetube 14 a wire 37 is positioned, the same being wound into a series ofcoils which are strengthened and reinforced by a central wire runningthe entire length of the coil as shown in Fig. 2. The coil wire 37extends the entire length of the tube and may be readily inserted orremoved from the tube whenever the coiupling 36 is removed. It desired.one or more disks 39 with openings therethrougggh may be interposed inthe length 01 the wire coil.

in operation the trough 13 is filled to any desired height with woodalcohol or the like and the fuel is entered into the tube 3% after whichthe alcohol is ignited. ihe needle alve 33 may be moved to close theorifice in the nozzle The alcohol is allo red to burn until the fuelwithin the tube is heated to a very high degree 0t temperature suchthat, when exposed to the air it will vaporize and mix therewith. lVhcnthe tube and tuol contained therein has been thoroughly heated theneedle valve may be opened by operating the handle 33 shown in 2, andthe fuel allowed to escape under 134.68- sure through the orifice innozzle It receives air tl'irough the openin 18 and mixes therewithpassing through the opening 17 into the compartment 8 where a certainportion of it passesv through the opening 16 and is ignited by theburning alcohol while the remainder passes to upper compartnrent orreservoir '7 from which it may pass through any uncovered opening 25 tothe burner which is associated therewith. The amount of fuel for one,two or three burners may be regulated by the regulation of the needleAny fuel which is not vaporized will run down the inclined floor 3 ofthe mixing coinpartment 9 to tne air inlet opening 18.

This construction may be placed in the fire box of a cook stove and toetwo burners having upper plates 23 may be used tor heating the upperremovable gridles while the rear burner may be used to heat the oven.Any number of the burners may be used and any burner which is not to beused. may have its fuel suppl cut oil very quickly and easily by movingvalve 2% to shutting-oil position. The mixed fuel and air pa ses aconsiderable distai'ice before it reaches any of the burners and isthoroughly mixed. The generation of the liquid into a gas takes place ata point considerable below where the gas is burned and there is littleor no danger of back-fire. When the fuel has once been heated by thealcohol the continuation of generation by heating the tube comes throughthe gas which passes out of openings l6 and is burned directly againstthe inner side of the tube 34. The coil Wire 37 with disks 39 aids thisgeneration as it is kept at a high degree of temperature at all timesand the fuel entering the tube has to pass around this wire for theentire length of the tube and through the disks before it escapes intothe compartment 9. Moreover any carbon which may deposit in the tube iseasily removed on removing the wire into tube may be kept clean withlittle or no trouble, and the disks serve to collect any solid. matterwhich may be in the fuel or which may deposit.

The construction described is relatively simple and has proven verysuccessful in practice.
